I watched some YouTube videos about karate recently. Watching these videos, I really wanted to do karate again. Actually I'm a member of a karate-ryuha but I don't go to dojo for a long time. One of the reasons I don't practice that is my sons no longer the member of karate group.
In the videos, many people punch and kick each other. It looks pain but everyone didn't give up their fight.
I think I need some physical exercises before rejoin the karate dojo otherwise I would get hurt in fighting.
